EIIIRAIM HAMBUJER, OF DETROIT, MICHIGAN.

CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 353.558, dated November30, 1886.

A pplieation tiled April 12, 1886.

To aZZ whom it may concern:

Be it known that l, Eri-IRAM HAMBUJER, of Detroit, in the county ofVayne and State of Michigan, haveinvented newand useful lm- 5 provementsin Car-Heaters; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in heatingfurnaces, especially designed for heating street or tramway cars wherethe room is limited, and which may be used-without interfering with theseating capacity of the ears.

zo while the grate, ash-pit section, and ash-drawer project downwardthrough the door, so that the dust arising from clearing the grate andash pit is kept from theinterior of the ear. Means are also providedwhereby, if the heater is situated midway between the two ends of thecar,

the smoke or exit pipe may be carried in both directions under theseat,and through the end walls of the car, and then up through the roofwhich covers the platforms, so that the driver 3o at one end and theconductor at the other may receive some benefit from the fire.

The invention consists in the pecular construction of the parts, theirlocation with relation to each other, and their combination, as

more fully hereinafter described.

Figurel is a front elevation of my improved heater. Fig. 2 is a verticallongitudinal section, looking toward the rear of the heater. Fig. 3 is avertical central cross-section from Fig. 4 is a horizontal sectionthrough thesmoke-jacket. Fig. 5 is a plan of the smoke-jacket, outercase, and feed-doors.

In the accompanying drawings,whieh form a part of this specitication,Arepresents the baseplate of the heater, which is formed with a well, asshown, and from which is pendent the ash-pit and draft-sectionB,designed to project through the floor C ofa car,while the baseplate isprovided with suitable feet, a, which 5o rest upon the floor.

Serial No. 108,620.

(No modrlJ,

D represents the tire pot,whicl1 is supported by the base A, and belowwhich is located a grate, E. This grate is pivotally set in a bracket,F, which latter is pivoted to a stud projecting from the wall ofthcash-pit section, its opposite end being supported by a dog, G. \Vhenit is desired to dump the grate, the free end ofthe dog is pushedinwardly, freeing the end of the bracket from the head ofthe dog,allowing bracket and grate to swing downwardly and deposit the contentsof the fire-pot into the ash-pit, from whence they vmay be readilyremoved through the door H.

The fire-pot is east or formed domeshaped,

and is provided with a feed-door, I, surrounding the ends and back oftheire-pot,and supported thereby is a jacket, J, into which the products ofcombustion pass'from the tire-pot through au opening formed in the sidesthereof, as at b. These openings have secured over them fingers K, whichmay be east,if found preferable, as an integral part of the lire-pot,and they are for the purpose merely of preventing the fuel or contentsof the lire-pot from falling into the chamberL,wl1ich is formed by thejacket .I aroundthe tire-pot, and either one of these openings, as maybe desired, or as ina'y be necessary from the position that the stove-inay occupy within the car, should be closed by a plate, N, theproduetsof combustion passwhence they find an exit at either end of the jacketat M, or through a verti cal pipe connected at M, as may be desired.This plate N is retained in position by means ofa bolt,d,whieh projectsoutwardly between the fingers K of the tire-pot, and receives upon itsouter end a nut, e, that will not slip between said fingers, the saidplate being ot' sufiicientsize and shape to fully close thedraft-opening at that point. For instance, if it is desired to have 'theproducts of combustion pass out upon the righthand exit, as in Fig. 4,there is a cap placed over the other exits, M M,and the right-hand exitof the iire-pot is likewise closed, thereby forcing the products ofcombustion to pass to the left (referring to Fig. 4) into thejacket J,thence around the fire-pot and out at the righthand end of thejacket, asis clearly shown by the arrows in the figure referred to, thereby IOO 'radiating their heat through such jacket into the car.

O is an external casing, that is preferably perforated at its sides andfront, While its top is imperl'orate. It forms an air-space, O',surrounding the smoke-jacket .I.`

It will be seen upon referring to Figs. 2 and 3 that the heated airthrown off from the iirepot and the jacket surrounding it will heat theair and caus a circulation of air through the outer space, O', as isclearly shown in Figs. 2 and 3, already mentioned. Of course, ifdesired,'both ofthe openings at the ends ofthe ire-pot'nnay be leftopen` particularly when a draft in a directline, as through M, isnecessitated by the position that the 4stove or heater may occupy in thecur. j

The case O is provided with a door, as P, which it is necessary in theconstruction shown to open before fuel can be introduced into theiire-pot. It is evident, however, that a door of the construction shownor any other door or .slide may be employed, as the mere function of thedoor is to provide acommunication through the perforated case Whichsurrounds thestove to the feed-door, and to serve as a shield or guardto prevent the clothes of any person occupying a seat'immediately abovecoming in contact with such portions of the stove as may be suiiieientlyheated to burn or Scorch them, While at the same time it gives a moreornamental finish to the structure. The space .0 between the re-pot andthe feeddoor P is preferably separated by suitable partitions from thespace O'.

In practice, the device being placed in a car and arranged substantiallyas shown and described, a fire is made in the {ire-pot, either as suchcars are usually constructed there will be leakage enough to insure arapid change of inconveniently so, owing to the air-space.

Il` desired, and it Would be preferable, the side of the car and'underside of the seat may be covered with sheet-iron, so as to prevent theradiation of too much heat to the seat immediately above.

. What I claim as my invention is.n

l. The combination, with the fire-pot provided with openings b, of thefingers K, secured over said openings, and the plate N, pivotallysecured to one of said iingers, lsubstantially as and for the purposespecitled.

2f. ,In acar-heater, the combinationvith the fire-pot, of the jacket J,surrounding the same and forming the chamber L, the fire-pot beingformed with openings affording communication with said chamber, platesfor controlling said openings, and one or more exitsV from said chamberthrough the said jacket, substantially as described. f

3. In a car-heatelg'the combination of the fire-pot, the jacket J,surrounding the same and formed with exits M M. and exit M at Vvice maybe somewhat Warm, it will not be right angles thereto, removable capsfor said Y exits, and the external casing, O, forming an air-spacearound thejacket J, substantially as described.

4. In a car-heater, the combination `of the repot, the jacket J,surrounding the saine and provided with exits M M M', as described, andremovable caps'therefor, the perforated external casing, O, providedwith feed-door P, and suitable partitions forming the feed-throatbet-Ween the tire-pot and the feed-door,and the pivoted plates N,substantially as described.
